I got a 440 block from George today and we're curious if you wizards can tell what it was used in. I gotta think it was probably a truck or motorhome??? The casting #4006630-440-1 6-9-76 and stamped very lightly on the plate by the head is 7T440TFH I'm not 100% sure about the 440 between the 7T and the TFH. The 440 Source guide does say this block has the widest webs and the big coolant holes plus the bigger motor mount feet. It hasn't been bored either as it is still 4.32" . Just curious.
